Supreme Court Declares Same-Sex Marriage Legal In All 50 States : The Two-Way "The nature of injustice is that we may not always see it in our own times," Justice Anthony Kennedy wrote after recounting the legal struggles faced by same-sex partners. Same-sex marriage supporters rejoice outside the Supreme Court in Washington, D.C., on Friday after the U.S Supreme Court handed down a ruling regarding same-sex marriage. The high court ruled that same-sex couples have the right to marry in all 50 states. Same-sex marriage supporters rejoice outside the Supreme Court in Washington, D.C., on Friday after the U.S Supreme Court handed down a ruling regarding same-sex marriage. The high court ruled that same-sex couples have the right to marry in all 50 states. The court noted the change in thinking, stating:  "Well into the 20th century, many States condemned same-sex intimacy as immoral, and homosexuality was treated as an illness. Later in the century, cultural and political developments allowed same-sex couples to lead more open and public lives. Extensive public and private dialogue followed, along with shifts in public attitudes. Questions about the legal treatment of gays and lesbians soon reached the courts, where they could be discussed in the formal discourse of the law."  For supporters of same-sex marriage, Friday's ruling comes as a long-awaited bookend to the Supreme Court's 2013 ruling that struck down the federal Defense of Marriage Act and required the U.S. government to provide the same benefits to both gay and heterosexual couples.
